Release notes for storage-operator - Container Service for Kubernetes

Container Service for Kubernetes (ACK) provides multiple storage components to enhance storage capabilities, such as automatic expansion of volumes, modification of disk specifications, and storage resource monitoring. The storage-operator component is used for unified lifecycle management of these components. This topic describes the usage instructions and release notes for storage-operator.

Introduction

Storage Operator is used to manage the lifecycle of storage components. Storage Operator runs as a Deployment, which deploys and upgrades storage components based on the default configurations inherited from the image and the custom configurations provided by ConfigMaps. This helps reduce the complexity of container development and maintenance.

Note Storage Operator can only be used in ACK clusters.

Default configurations: Storage Operator provides the default configurations of storage components. The default configurations vary based on the version of Storage Operator.
Custom configurations: ConfigMaps can be used to define custom configurations of storage components, such as version information, and whether to install the component.

Storage Operator preferably uses custom configurations. The default configurations are used only when the custom configurations are not specified.

Note

Each image of Storage Operator contains the default configuration file.
When Storage Operator runs as a Deployment, the Deployment reads configurations from a ConfigMap file that is mounted on the Deployment and contains configurations of storage components.
Storage Operator determines whether to deploy and upgrade a storage component by combining the default and custom configurations.

Usage notes

For more information about how to use the storage-operator component, see Use storage-operator to deploy and update storage components.
